Fibre Optic Sensors for Structural Health Monitoring of Aircraft Composite Structures: Recent Advances and Applications. Department of Industrial Engineering—DIN, University of Bologna, Forlì 47121, Italy Academic Editor: Vittorio M.N.
Passaro Received: 24 May 2015 / Revised: 3 July 2015 / Accepted: 23 July 2015 / Published: 30 July 2015 In-service structural health monitoring of composite aircraft structures plays a key role in the assessment of their performance and integrity. In recent years, Fibre Optic Sensors (FOS) have proved to be a potentially excellent technique for real-time in-situ monitoring of these structures due to their numerous advantages, such as immunity to electromagnetic interference, small size, light weight, durability, and high bandwidth, which allows a great number of sensors to operate in the same system, and the possibility to be integrated within the material.

Note – this blog-post discusses the use of the 13553 – 13567KHz band under FCC Part 15 regulations in the US.
Although it is a worldwide allocation, rules vary according to where you are. Off the top of my head, I do know that there are HiFER beacons operating in some countries on the European continent, but that is the extent of my knowledge of this type of operation outside the US. Before saying anything else, I must note that even though the earlier projects which were named after my cats were not my designs, I did at least contribute enough of my own input that I could perhaps get away with naming them.

A Review of the Bonito 1102S RadioJet 24 bit IF Receiver. Bonito’s Dennis Walter at the Bonito booth in Hara Arena at the 2012 Dayton Hamvention At the Dayton Hamvention this year, I met Dennis Walter, who is with Bonito, German manufacturer of the 1102S RadioJet.
Dennis was kind enough to loan us a radio for review on SWLing.com. I have been evaluating the Bonito 1102S RadioJet over the course of eight weeks and have formed some impressions about its performance. Meet FM antenna design challenges in portable devices.

Equipped with analogue High-IF circuit, multi-conversion and DSP decoding technology, PL-880 has great performance in its sensitivity, selectivity and the interference of mirror stations (image rejection). Besides these technological advances, the introduction of the Auto Sorting Memory function in Tecsun’s latest top receivers provides greater user friendliness and convenience in using stored stations. And to further enhance listening enjoyment, PL-880 is fitted with Class AB type Audio Power Amplifiers and ultra-dynamic full range speakers. Special Functions: Multi-conversion processing of incoming radio signals to reduce interference. Squelch control SW Single Side Band (SSB): individual reception of Upper Side Band (USB) and Lower Side Band (LSB) Auto-sorting memory: sorting stored stations automatically according to meter band and frequency, removes duplicate stations.

All Things Radio. Thanks to a blog posting over at SWLing.com I just found out Heathkit is back and about to release their first build-it-yourself kit, with the promise of many more to come.
Heathkit, for those who may not be familiar with the name, was a legendary producer of kit radios (and TVs, and even computers) long ago. As great as the kits were, the instruction manuals were like an electronics course in themselves. The Radio Kitchen.
